JOSEPH E. CRISP, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE COPE- LAND BOOT-TREEING MACHINE COMPANY, OF HARTFORD, CONN.

BOOT-TREEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,210, dated October 12, 1880.

Application filed July 8, 1860.

To all whom it may concern Be it known that I, JosEPn E. CRISP, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented an Improvement in Boot-Treeing Machines, of

which the following is a specification.

This invention relates to the following-described improvement in boot-treein g machines, reference being had to the accompanying 1o drawings, forming a part of this specification in explaining its nature, in which- Figure 1 represents a portion of a boot-tree in section and a rubbing-tool in elevation. Fig. 2 represents a plan of a rubbing-tool inverted,

i5 and Fig. 3 a crosssection thereof on the line :0 m of Fig. 2.

It is desirable in some instances to provide the rub stick with automatic reciprocating motion, and at the same time provide the same with means whereby its use may be directed by the operator; and my invention relates to means for accomplishing this result.

A represents the rub-stick. It is pivoted at a to the frame B. This frame is provided with the handles 0, and furnishes a bearing for the crank D, which has a bearing on the shaft d, and which is revolved in the recess d of the frame by means of the flexible shaft E. The crank D imparts a reciprocating move- 0 ment to the rub-stick by means of the block (1 upon one end and the recess 61 in the rubstick, in which the block d is reciprocated by means of the crank.

It will be observed that, as the rub-stick is 3 5 pivoted at one end, a considerable range in the (No model.)

width of the stroke is provided for. By moving the tool laterally upon the boot-tree when the outer portion of the rub-stick is operating a greater surface of the boot-tree is being operated upon, and when the portion near the pivot is being used a less portion is being Worked.

The frame B is weighted sufficiently to provide the requisite steadiness and to relieve the frame and handles of the machine from vibra- 5 tion. If desirable, the tool may be suspended by means of a cord and pulley and balance- Weight, or in any other desirable way.

The boot-tree which I prefer to employ with my invention is that described in my Letters 0 Patent, Reissue No. 9,124, or that described in my pending application, filed May, 1880.

[n the operation of treeing the boot is suitably tempered and the filling composition applied. The rub-stick is then brought to bear upon the work, and under guidance of the operator is moved over the tree, performing the rubbing operation in order, as his experience or skill may determine.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States The combination of the frame B and rubstick A,'the crank D, shaft d, and the flexible shaft E, substantially as and for the purposes described.

J. E. CRISP.
